A lication filed December 6, 1920. Serial no. 428,736.

To all whom it may concern:

Be it known that I, FRITZ FINoKH, residing at. 18 Kronprinzenstn, Essen-cn-the- Ruhr, a citizen of the German Republic,

also.

have invented a certain new and useful lm provement in a Vehicle Discharging from the Bottom (for whichI have filed an appli cation in Germany Aug. 13, 1919) of which the followingis a specification.

This invention relates to vehicles discharging from the bottom which have two bottom doors opening automatically under the action of the weight of the load and which are in hinged connection with the side walls of the vehicle when the discharging takes place, said side walls being movable likewise. The object of the invention isto provide a selfdiseharging vehicle of this kind which is articularly adapted to be loaded with goods which tend to become jammed on dischargmg.

One embodiment of the subject matter of the present invention is illustrated in the accompanying drawing, in which- Fig. 1 shows a section through the discharging vehicle ready for receiving the load,

Fig. 2 is a similar section through the vehicle after the discharging operation.

On the sills c of the underframe A of the vehicle which has fixed end walls A, there are swingingly mounted the bottom doors B. When in the loading position these two doors B are inclined towards the middle line of the vehicle and bear against each other with their lower edges, so as to form a hopper, and can be locked in this position by means of a locking device, one embodiment of which is shown in the drawing. It comprises a latch h pivoted to one of the doors B and adapted to engage a pin 2' rigidly fixed on the opposing door. At their upper edges the side walls O of the vehicle are swingingly suspended from the end walls A and bear, when in the loading position, against levers D which form abutments and are formed by springs. The levers D are mounted on side shafts D fixed on the end walls A Parallel to the side shafts D there are rotatably mounted on the end walls A cam shafts E, on both sides of the vehicle, which are coupled to each other, at each end wall. by means of links F.

On the shafts E which can be fixed in different angularpositions by means of a set Specification of Letters Patent. Patented Aug. 29, 1922.

screw K engaging one of severalholes a i in one or the end walls A are mounted cams I e which form abutments for the levers D and therefore indirectly for the side walls C V hen the vehicle is in the loading position (Fig. 1), the sidewalls are held.

-ment of these doors commences under the ac tion of the weight of the load. when this takes place, the distance between the upper edge of the bottom doors and the side walls diminishes, and after a short interval of time the bottom doors strike against the side walls with a considerable force. the further course of the discharging operation, the side walls are in a sliding contact with the bottom doors and are swung inwardly by the latter. By the bottom doors striking the side walls so strong a shock is produced that even a load which would otherwise tend to become iammed is completely discharged.

By the device for adjusting the distance between the side walls and the bottom doors. the advantage is obtained that the amount of this distance may be fixed with respect to the particular properties of the load.

Moreover, it has been determined by experiments. it is often sufficient to adjust the said distance between the side walls and bottom doors on one side of the vehicle only.

I claim:

1. A vehicle discharging from the bottom having bottom doors opening automatically under the action of the weight of the load. movable side walls and means for establishing a sliding contact between said side walls and said bottom doors on the discharging movement of said parts.

2. A vehicle discharging from the bottom having bottom doors opening automatically under the action of the weight of the load, movable side walls, means adapted to hold at least one of said side walls at a distance from the corresponding bottom door when the parts are in the loading position and by means of the abutment levers D at a dis- 1 Then, in I means for establishing a sliding contact between said side walls and said bottom doors on the discharging movement of said parts.

3. A vehicle discharging from the bottom having bottom doors opening automatically under the action of the weight of the load, movable side Walls, abutments adapted to hold at least one of said side walls at a distance from the corresponding bottom door when the parts are in the loading position and means for establishing a sliding Contact between said side walls and said bottom doors on the discharging movement of said arts.

p 4. A vehicle discharging from the bottom having bottom doors opening automatically under the action of the weight of the load, movable side walls, abutments adapted to hold at least one of said side walls at a distance from the corresponding bottom door when the parts are in the loading position and means for establishing a sliding contact between said'side walls and said bottom doors on the discharging movement of said parts, said abutments being adjustable in order to change the distance between said side walls and said bottom doors with respect to the properties of the load.

5. A vehicle having normally locked bottom doors opening, when released, automatically by the weight of the load, movable side walls, and adjustable means for holding at least one of the movable side walls in a predetermined position relative to the said doors.

The foregoing specification signed at Essen, Germany, this 23rd day of July, 1920.
